spring2 整合 Dwr(把DWR的配置写到Spring的配置文件)
Spring 2基于XML Schema的配置,Spring 2通过XML Schema配置方式极大地简化的其配置,而且使得第三方扩展变为可能
<beans xmlns ="http://www.springframework.org/schema/beans" xmlns:xsi ="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation ="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.0.xsd" >

打开DWR的jar包中META-INF/spring.schemas文件,内容如下:
?
http\://www.directwebremoting.org/schema/spring-dwr-2.0.xsd=org/directwebremoting/spring/spring-dwr-2.0.xsd
?
?
我们在配置Spring 2时,应在名称空间中加入以下配置:
<beans xmlns="http://www.springframework.org/schema/beans" xmlns:dwr="http://www.directwebremoting.org/schema/spring-dwr" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.0.xsd http://www.directwebremoting.org/schema/spring-dwr http://www.directwebremoting.org/schema/spring-dwr-2.0.xsd">
?
以下是我整个spring的配置及一些java类

package com;public interface TestServiceInf {public boolean checkedUser(String userName);}?
TestServiceImp.java
